Singapore is supplying an additional six million gallons of potable water to Johor a day, amid a dry spell affecting the Sungai Layang dam in Johor Baru.

This is on top of supplying potable water commencing June 4, on request of Johor water regulatory body Badan Kawalsetia Air Johor (Bakaj), Singapore Public Utilities Board (PUB) said in a statement.

“This latest request will see Singapore temporarily supplying 22 million gallons a day of potable water to meet Johor’s needs in the present dry weather situation,” it said in a statement.

It added that PUB has over the years supplied about 16 million gallons of potable water to Johor.

An additional five or six million gallons a day of potable water was supplied from Aug 14, 2015 to Jan 8, 2016, it said.

It added that it would not affect Singapore’s domestic supply, although reservoir levels in the island republic have dipped from 33 percent to 40 percent to an all-time low in April 2016.

Singapore’s Linggui Reservoir yields water from the Johor River.

Under the 1962 Water Agreement, PUB is entitled to draw up to 250 million gallons a day of raw water from the Johor River daily, while Johor can supply up to five million gallons a day of raw water to Singapore.
